Problems after upgrading to Xcode 10: Build input file cannot be found

Question

I upgraded my Xcode SDK to version 10 last night and then find I cannot build.

I\'m getting this error:

Build input file cannot be found: \

Answer 1

In my case, the file (and the directory) that XCode was mentioning was incorrect, and the issue started occurring after a Git merge with a relatively huge branch. To fix the same, I did the following steps:

• Searched for the file in the directory system of XCode.
• Found the errored file highlighted in red (i.e, it was missing).
• Right clicked on the file and removed the file.
• I tried building my code again, and voila, it was successful.

I hope these steps help someone out.

Answer 2

File>Project Settings>Change Build Systems to Legacy Build Systems

Answer 3

Just check the path to .plist file in Build Settings of your target

Answer 4

None of the above worked for me, but this did:

1. Open project in Finder, right click on your .xcodeproj file and show package contents
2. Open project.pbxproj in a text editor
3. Find the reference to your missing file
4. Edit path = "path/to/file.swift" to the actual location on disk and save the file.
5. Rebuild the project
